A range of 3-in-1 current transformers combine threetraditional current transformers in one moulded case. 3-in-1 current transformers can be directly installed next to a three-phase moulded case circuit breaker, thus savinginstallation time where fitting three standard individualcurrent transformers would be required. The M3N1 range of current transformers offers primary currents between60-630A with 5A secondaries with up to class 0.5 accuracy performance.
